I am trying to write a function that will access a column of a data frame
without having to qualify the name of the data frame column as long as the name
of the dataframe is passed to the function. As can be seen from the code below,
my function is not working:
df <- data.frame(x=1:10,y=11:20)
df
test <- function(column,data) {
print(data$column)
}
test(x,df)
I am trying to model my function after the way that lm works where one needs
not qualify column names, i.e.
fit1<- lm(y~x,data=df)
